I have a1988 pro 17 Bass Tracker that leaked like a sieve. I found a place in Charlevoix that I could order some closed end rivets. I drilled out the old rivets ,squirted some good marine silicant in the holes and re-riveted the whole boat. no more leaking rivets. It pays to have a nephew who is in the auto repair business,as he loaned me an electric rivet gun.
